RO System Pressure Controls | Pump Protection Switches

Intro: Protect your water treatment systems with reliable industrial pressure switches. Our high-quality switches ensure safe operation of RO systems, pumps, and filtration equipment with precise pressure monitoring and automatic shutdown capabilities.

What Are Water Treatment Pressure Switches?

Pressure switches are essential safety devices that monitor system pressure and automatically activate or deactivate equipment based on preset pressure thresholds.

Key Functions:

• System Protection: Prevent damage from over-pressure conditions
• Equipment Safety: Avoid pump dry-running and cavitation
• Process Control: Maintain optimal operating parameters
• Automatic Operation: Enable unmanned system functionality

Types of Pressure Switches for Water Treatment

1. Low Pressure Switches

• Application: Pump protection and dry-run prevention
• Setting Range: 0-100 PSI
• Typical Use: RO pre-treatment monitoring

2. High Pressure Switches

• Application: Membrane and vessel protection
• Setting Range: 50-600 PSI
• Typical Use: RO high-pressure pump control

3. Differential Pressure Switches

• Application: Filter monitoring
• Setting Range: 5-150 PSI differential
• Typical Use: Cartridge filter condition indication
